BLANK-FEED MECHANISIW FOR CAN-CLOSING MACHINES.

machines in which a packing material is applied to the lids.

Though the feeding mechanism has been described with reference to a machine of the character indicated, it should be understood, that it may advantageously be used in machines of other character.

The object of the improvements is to provide a feeding mechanism, whereby the blank can be fed to the machine in, a simple and reliable way, and which requires little space.

For the purpose ol explaining the inven tion, an example embodying the same has been shown in the accompanying drawing, in which the same letters of references have been used in all the views to indicate corresponding parts.

In said drawingFigure 1, is a side View, partly in section, of the feeding mechanism,

1 showing in addition the part of the cooperating machine to which the blank is to be supplied, Fig. 2, is a plan of the parts shown in Fig. l, and Fig. 3, is a side view of a modification of a detail of Figs. 1 and 2.

In the example illustrated in the drawing, a horizontal table at is mounted on a vertical shaft f rotatably mounted in a suitable hearing 0. On the said table a plate or catch 0 is provided which is ada ted to be moved, by the rotation of the ta le (Z, below a vertical chute a receiving the can bottoms or lids b. The chute a is mounted in any suitable Way on the frame of the machine. Within the same, the blanks b are so arranged, that the catch or plate 0, when moved below the chute a, engages in the hollow ol the bottom or lid, so as to carry the same alonp in the direction of its travel. For this purpose, the lids or bottoms are piled up within the chute at an angle to the surface of the l I, l

-Feed Mechanisms for (Yarn 5 table (I, and with their hollows directed toward the same. By the plate (:1 the blanks are securely i'uidcd lmvards the n'lachinc. lhough a guide we or the like is not provided. As shown in the drawing, the plate (I is yicldingijly mounted on the lablc d, so that it can brmovcd ou'l oi ihc surl'mc oi' the latter. And when thus lllOtgll out the plane of the table (I it will permit the lid or bottom carried alone there j; lo be removcd from the table d by means oi a guide bar 72. in the example illustratml, the plnlo c is secured to a lever 7; rocking on a pivot i secured to the lower face oi the table (I.

Opposite the chute u a cam piece is provided, wl'icroby the plate 4 moved upx-Jzud slightly be'l'ore ii arrives bel w th chute o. and in time to take hold ol' the lowcrnu'ist one of the blanks l). ,llri'ore, however, the

date i and the lid or l ottom carried tlwrcbv 7 upon the forward lira *ol ol' the table d, z. No. in front of the guide bar it, the cam Z permits the lever l.- to rock downward, so that lhn plate 0 is shilled out ol'thc ph: e or the i (t. Now the lid or bottom can be moved b the bar it away from the table (I and onto the machine, the receiving element ol' which, in the example illustrated, is a can bod is resting upon the well known lilting punch m" of a can closing machine.

At the rear oi the plate 0 a rib n is prclcrably provided, which, in combination with the bar 72, assures the feed of the blank away from the table (I. The tabled may be rotaled by any preferred means, such for example as toothed gears one of which is secured to the lablr. To sccure a proper cooperation oi llul'ccdingr mechanism with the nnichinn the driving mechanism of the latter is opcrativcly connectcd with that of the table (1'.

To hold the lids or botloins I) piled up within the chule (1. in their inrlincd positions in which they cairbe caught by the plate r, a lug: c or the like is provided wilhin the chute, whereby the lowermost one .ol the lids I) is supported at one side, wliilc it rests, with its opposite side, on the table (I. A further means to hold the blanks in their inclined positions is shown in Fig. .2. in this example the horbconlal cross-soction oi the chute a is made elliptical or rectangular. One ol' the diameters ol the ellipse, or one ol' the sides ol the rectangle, is equal to the diameter of the lid, (or. in case of square lids. to the side of the same), while the other one till , along, while u on its backward travel it releases the blan so as to discharge the same to the machine part m. In this case, the plate or catch 0 is preferably made in the form of a wedge, as shown in Fig. 3.

I claim:

1. The combination with blank operating means and magazine means for holding a series of blanks, of blank feeding means comprising a rotatable table provided with a catch movable across the discharge end of the magazine means to engage and remove a blank therefrom, said catch being movable with respect to said table into or out ol' engagement with the blanks, means for operat ing the catch first to engage and remove a blank from said magazine means and subsequently to disengage the removed blank, and a stationary guide overlyin the table and deflecting the disengaged b anks iroin the table to the blank operating means.

2. The combination with blank operating means and magazine means for holding a series of blanks of blank feeding means comprising a movable table provided with a catch arranged to travel across the discharge end of the magazine means. and to engage .and remove a blank therefrom and means for stripping theblank from the catch and for removing the blank, from the table, said strip ing means eflecting the delivery of the blank to theblank operating means.

3. The combination with blank operating means and magazine means comprising a chute for holding a series of blanks, of a table provided with a catch movable across the discharge opening of the magazine means, said catch engaging and removing a blank from the magazine means in such movement, means for moving the catch with relation to the table and out of engagement with the blank and means for stripping the blank from the catch and for effecting the transfer of the stripped blank from the table to the blank operating means.

4t. The combination with magazine means .for holding a series of blanks, of a movable table, a catch mounted on the table and movable with -.respect to the plane of the table,

said catch being arranged to travel across the discharge end of the magazine means, and means for moving the catch to engage a blank and to remove the same from the magazine means, said means having operation to release the catch whereby the latter disengages said blank at a point in the subsequent travel of said table.

5. The combination with magazine means for holding a series of blanks of a table, a catch movable across the discharge end of the magazine means, means for operating the catch to engage a blank and remove the same from the magazine means and to subsequently release the catch whereby the latter moves out of engagement with the blank, which is then supported on said table, and means for stripping the disengaged blanks from the table.

6. The combination with magazine means for holding a series of blanks, of a movable table, a catch ivotally mounted on the table and movable with respect to the latter, said catch being arranged to travel across the discharge end of the magazine means, and cam means for moving the catch to engage a blank and to remove the same from said magazine means and to subsequently release the catch whereby the latter moves out of engagement with the blank, which is then supported on the table.

7. The combination with magazine means for holding a series of blanks, of a movable table, a catch mounted upon and movable with respect to the table, said catch being arranged to travel across the discharge end of the magazine means, means for operating the catch to engage a blank and to remove the same from the magazine means and to subsequently release the blank, and means for stripping the released blank from the table.

8. The combination with magazine means for holding a series of blanks of a table having a catch movable across the discharge end of the magazine means and having operation to engage and remove a blank from said magazine means, and means for engaging the removed blank to strip the same from the table.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
